Frequency domain linear prediction (FDLP) is a technique for auto-regressive (AR) modeling of Hilbert envelopes of the signal. The model is derived by the application of linear prediction on the discrete cosine transform (DCT) of the signal. In this paper, we propose modifications of the basic FDLP approach for deriving high resolution envelopes. We determine various factors which affect tempor...

We show that the complete information that is available after an image has been encoded is not just an approximate quantized image version, but a whole set of consistent images that contains the original image by necessity. From this starting point, we develop a set of tools to design a new class of encoders for image compression, based on a set decomposition and recombination of the image feat...

We have compared simulated and measured scattering matrices of a size distribution of olivine particles at wavelengths of 633 and 442 nm. The computations were carried out for size distributions of irregularly-shaped compact particles with different average projected areas using the discrete-dipole approximation (DDA). The results of the comparison show that the model of irregularly-shaped part...

This paper is to show that all but one discrete models used for population dynamics in ecology are inherently paradoxical that their predications cannot be independently verified by experiments because they violate a fundamental principle of physics. The result is used to resolve an on-going controversy regarding ecological chaos. Another implication of the result is that all continuous dynamic...

Measuring the dependence between random variables is one of the most fundamental problems in statistics, and therefore, determining the joint distribution of the relevant variables is crucial. Copulas have recently become an important tool for properly inferring the joint distribution of the variables of interest. Although many studies have addressed the case of continuous variables, few studie...

Testing of hypotheses for discrete distributions is considered in this paper. The goal is to develop conditional frequentist tests that allow the reporting of datadependent error probabilities such that the error probabilities have a strict frequentist interpretation and also reflect the actual amount of evidence in the observed data. The resulting randomized tests are also seen to be Bayesian ...

We apply the discrete dipole approximation (DDA) to estimate the radiation pressure cross section for fluffy aggregates by computing the asymmetry parameter and the cross sections for extinction and scattering. The ballistic particle—cluster aggregate and the ballistic cluster—cluster aggregate consisting of either dielectric or absorbing material are considered to represent naturally existing ...

ONE of the most characteristic clinical features of idiopathic hypertrophic subaortic stenosis (IHSS) is the striking variability in the intensity of the symptoms which accompany this disease. It has become clear recently that the severity of obstruction to left ventricular outflow is variable in IHSS and may be altered by a variety of physiological and pharmacological stimuli.' Alterations in ...

PRECISE ANATOMICAL ANALYSIS OF STENOTIC LESIONS OF THE LEFT VENTRICULAR outflow tract (LVOT) in discrete subaortic membranous stenosis (DSS) and hypertrophic obstructive cardiomyopathy (HOCM) is challenging due to their complex nature (1,2). In the present study, we clarified the difference of the geometry and dynamic change of LVOT area using en face views of the LVOT in 6 patients with DSS an...
